These verbs are called multidirectional (like "ходить", simple aspect) and unidirectional (like "идти", continuous aspect):
(1) "Ходишь в университет" - multidirectional (or, like you say, used to show a repeated action - simple aspect, in terms of English grammar);
(2) "Идёшь в университет" - unidirectional (or used to show a one-time/single action - continuous aspect). In this case, very similar to English "Are you going to university today?" (continuous aspect, as we know, shows an intended future action, not only the current one)
